The FWS8 Motorized Filter Wheel can hold up to 8 different filters (bandpass, neutral density, interference).
The Filter Wheel is easily mounted on the entrance slit of a spectral instrument.
A stepper motor is used for filter interchange. Direct control from a spectral instrument is provided for Filter Wheel operation.
The Filter Wheel FWS8 comes with 3 standard filters having parameters as follows:
